Curious. What cryptocurrency has implemented sharding successfully, and how does transfer of value happen between shards?
https://bitcointalk.org/index.php?topic=5109561None has implemented it though, otherwise BTLightning would have already crashed.
Because what I want to know is, if miners/stakers are required to have all the shards, or trust their peers for the integrity of each shard?
Miners mine all shards, users verify few, one or none.
All shards? Doesn't that NOT change anything except making a non-mining "full node" less than what is in a "non-sharded" blockchain?
it is the distribution of "power" not distribution of "load". the power to make decisions, enforce rules, keep the employees (eg. miners) in line with those rules,... the fact that each node does all of this on its own means they are not relying on anybody else and make their own decisions hence keeping the network decentralized.
Great answer.
I think the next step in blockchains is distributing load - storage, CPU, network, etc. in a fair and trustless way, while maintaining the distribution in power.
Blockchains such as bitcoin are vastly over-redundant.
But it has to be.
